Error, unknown recipe!
To make the cracked variant, first craft regular bricks (see above). Then smelt them in a furnace or any type of forge. The cracked slabs, stairs, and walls can now be made on an Angmar crafting table, using the normal Minecraft recipes.

Only the bricks (normal or cracked) can be put into the world and then right-clicked with gulduril to create a (cracked) gulduril Angmar brick. It will appear to be enveloped in a green sheen, similar to gulduril Mordor bricks and gulduril Dol Guldur bricks. These blocks can be used to make Morgul portals. After creation, you can harvest the blocks with a silk-touch pickaxe. A normal pickaxe will only yield the original block.
